Rendering Profiles Implementation

This is a page to track all the issues related to the general
redesign/refactoring of project “profiles” (a.k.a. presets or
templates) and all the related user interfaces (Project settings dialog,
Rendering dialog, Startup wizard). There are dozens of bug reports and
mockups scattered in the bug tracker. This page is an attempt to bring
those into a cohesive whole.

Mockups

Note: the selected preset must default to “Last settings”, except if the
last settings were == one of the presets.

Current implementation

Old and needs work:

Rendering dialog

Should basically be a clone of the project settings dialog with a couple
of additional options.

Current implementation

Needs work:

Startup wizard

Implement the first part (the start wizard itself; see the
screenshot above and bug
615570)

When clicking “Create new project...”, simply call the new
“Project settings” window (see mockup above). That dialog defaults
its preset to the “Last used settings” project preset/profile, this
way the user doesn't have to do more than 2 clicks.
